![]() These are plain text files that you can open with a text editor, such as gedit on Linux, or with the command open -e on a Mac. ![]() This type of analysis is referred to as pointwise assessment of streamline tractography attributes (PASTA). This file contains diffusion measures averaged at consecutive cross-sections of the pathway, resulting in an along-tract profile of each diffusion measure. This file contains diffusion measures averaged over the whole pathway. There are two types of statistics files that are created for each white-matter pathway: This section of the tutorial will teach you how to extract statistics on anisotropy and diffusivity measures for the white-matter pathways reconstructed by TRACULA. Thank you for your patience.įor each new terminal that you open, you must do:Įxport SUBJECTS_DIR=$TUTORIAL_DATA/diffusion_tutorial/fs ![]() ![]() For now, please ignore any references to the tutorial data and try to follow along using your own data. The new tutorial goes beyond what was possible with the tutorial data set that was previously available for download. Please bear with us while we update the tutorial data set for the new version of TRACULA. ![]()
